Working principle of the generator is simple. PWM generationīlock diagram of the PWM generator is shown in Fig. It is simulated using ModelSim, a multi-language (hardware description language) simulation environment from Mentor Graphics and tested on Basys 2 FPGA development board from Digilent.

How can you use UVVM to detect these corner cases?Įspen Tallaksen, Founder and CTO of Bitvis.Įspen is also the author and architect of UVVM and founder of previous Bitvis. Independent of tools, what is required to detect these corner cases? Why are the common solutions not working?

What is the probability of detecting or testing such a corner case? What does a typical error prone code look like?

This webinar will explain these corner cases in more detail and then show why they often result in bugs, why these bugs are often not detected, and how you can detect them. For this simple example however, most designers will handle this correctly, – but for more complex examples – including something as simple as a UART, this type of corner case is extremely error prone. Then a typical cycle related corner case is if you read/reset the counter in the same cycle as a new event occurs – risking strange behaviour in many ways. To explain this in a simple way, – a cycle related corner case is for instance if you have an event counter where the number of counted events is critical and you read and reset this counter at regular intervals. Presenter: Espen Tallaksen, CEO of EmLogicĬycle related corner cases are probably the worst and main reason for undetected bugs on many FPGAs.
